The child’s mother remained hospitalized Tuesday in a medically induced coma.

Bruno let himself into the woman’s apartment located at 110 Rutgers Ave., and attacked her and another woman when they got home early Friday, authorities said. He repeatedly stabbed both women and then pushed his ex-girlfriend into an air conditioner, causing her and her 3-month-old child to go through a window and fall three stories.

Bruno then climbed down the apartment’s fire escape, authorities said, and started beating the woman again, this time using a table he found in the backyard.

Bruno was arrested last Friday after he was found hiding in the refrigerator of a vacant second-floor apartment in Belleville, N.J.

Bruno’s niece was apologetic following the arrest.

“I’m shocked, it’s crazy. I feel bad for the baby and his mom and the other lady who was trying to help them,” Ashley Archelus said.

Archelus and her mother — Bruno’s sister — live in the apartment next to where Bruno was eventually caught.

“We were all inside and they said that they caught him in the next apartment in the fridge,” she said. “We didn’t know he was coming. He just came out of nowhere, because he just comes once in a blue.”

Last week, Police Chief Thomas Comey expressed the outrage of his community in describing the violent and terrifying scene.

“I’ve been doing this 32 years, and every time you think you’ve seen it all, and you’re shocked, something comes along and shocks you again,” Comey told reporters.
